Caution: Remove the fuel tank cap and relieve the fuel system pressure before servicing the fuel system in order to reduce the risk of personal injury. After you relieve the fuel system pressure, a small amount of fuel may be released when servicing the fuel lines, the fuel injection pump, or the connections. In order to reduce the risk of personal injury, cover the fuel system components with a shop towel before disconnection. This will catch any fuel that may leak out. Place the towel in an approved container when the disconnection is complete.

1. Relieve the fuel system pressure. Refer to Fuel Pressure Relief .



2. Grasp both sides of the quick-connect fitting. Twist the female connector 1/4 turn in each direction in order to loosen any dirt within the quick-connect fitting.

Caution: Wear safety glasses when using compressed air in order to prevent eye injury.




3. Blow any dirt out of the quick-connect fitting using compressed air.



4. Squeeze the plastic retainer release tabs and pull the connection apart.




Notice: Use an emery cloth in order to remove rust or burrs from the fuel pipe. Use a radial motion with the fuel pipe end in order to prevent damage to the O-ring sealing surface.

5. Use a clean shop towel in order to wipe off the male fuel pipe end.
6. Inspect both ends of the quick-connect fitting for dirt and burrs.
7. Clean or replace the components and assemblies as required.

Caution: Always apply a few drops of clean engine oil to the male pipe ends before connecting the fuel pipe fittings in order to reduce the risk of fire and personal injury. This will ensure proper reconnection and prevent a possible fuel leak. During normal operation, the O-rings located in the female connector will swell and may prevent proper reconnection if not lubricated.

1. Apply a few drops of clean engine oil to the male fuel pipe end.



2. Push both sides of the quick-connect fitting together in order to snap the retaining tabs into place.



3. Once installed, pull on both sides of the quick-connect fitting in order to make sure the connection is secure.
